GENERAL
Whether you're mixing sound for a band, schoo l
auditorium, theater, AN pr oduct ion studio, or
night club, RAMSA audio mixmg conso l es can
enhance the qua l ity of your mix. That 's because
the new RAMSA audio mix ing consoles offer
features that are usually found on larger, more
expensive conso les.
The new RAMSA audio mixing consoles are
available in three different configurations : the
eight-input WR- S208, twelve-input WR-S212
and sixteen-input WR-S216. But whatever size
console your application demands, all three
models offer a variety of features designed for
optimum performance .

IMPORTANT NOTICE
1) The mixer OL.:'.puts are available In a f ew seconds
after turning on the power switch. It takes approx-
il~lately 5 minutes for the mixers performance to
be Lily stabilized. C lic k sou nds mig ht be heard
before it is fully warmed up.
21 When using the input selector switch while the
phantom power is tur-ed on, turn tile output fader
down to avoid any popping noise whl::h might
damage the speakers or other equipment con-
nected to the mixer.
CAUTION:
.Jo not connect unbalanced microphones to the
r:iixer wh en using phantom power. Power supply
ilnd "Tl ic rophone may be daM aged.
3) The phantom power supply for mic inputs employs
a slow start system to avoid c::ck sounds f~om be-
Ing produced. Allow 1 minute after pressing phan-
tom power SWltc;-, for voltage to stabilize.
4) When con'lectlng and dlscon'lectlng a rT';crophone
while the p"'antom power is turned on, click sounds
may be heard . Be sure to turn on the phantom
power aLer connecting t-e microphones to the
mixer . When oisco n necting mi crophones, wai t at
least 20 sec . after turning phantom power off .
4. Tile WR-S 212 and WR-S 216 employ 60 mm car-
bon faders for the monitor and send outputs.
5. The WR-S212 and WR-S216 are provided with
stereo output )cks for control room monitOring.
6. Solo level can be adjusted With the solo control
knob, and the solo ndlcator I.ED is located near the
solo control knob to confirm solo monito'ing.
7. The output circui~ contains a built-in sunrning
peak Indicator LED, which indicates distortion when
m~ltiple inpJ ~ signals are mixed.
5) Fa rinse rtlon at the in put patch points, use a Y-
shaped adaptor cord, wired as tip; return, ring; send
and sleeve ; comll'on on a 114" TRS phone plug.

pin 1 (GND) (Common).
Before turn ing this switch on or off, be sure to shift
each output fader to the minimum position to prevent
click noise.
